Embodiment Construction
[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] In this embodiment, the following formaldehyde detection method can be realized by a simple formaldehyde detection device. The formaldehyde detection device includes a controller and a first formaldehyde sensor and a second formaldehyde sensor with different reaction intensities to interfering components. The first formaldehyde sensor, the second formaldehyde sensor Diformaldehyde sensors are respectively electrically connected to the controller. When working, the controller calculates according to the detection data transmitted by the first formaldehyde sensor and the second formaldehyde sensor, and then outputs the concentration value of formaldehyde in the environment.
[0030] The response intensity of the first formaldehyde sensor to the interfering components is F1, and the response intensity of the second formaldehyde sensor to t...

The invention relates to a formaldehyde detection method, which acquires the detection data and response time of two formaldehyde sensors with different reaction intensities to interference components in the same environment; compares the response times of the two formaldehyde sensors to determine whether there is an interfering gas, and according to the interfering gas The formaldehyde concentration value in the environment is calculated from the judgment result and the detection data of the two formaldehyde sensors. In the formaldehyde detection method, the reaction time of the two formaldehyde sensors will be significantly different when interference components appear, and the interference situation can be judged, and a more accurate formaldehyde detection value can be calculated. The present invention also relates to a formaldehyde detection device, comprising a controller, a first formaldehyde sensor and a second formaldehyde sensor with different reaction intensities to interfering components, the first formaldehyde sensor and the second formaldehyde sensor are respectively electrically connected to the controller, the The formaldehyde detection device is a formaldehyde detection device with simple detection, the ability to judge interference, low cost, and accurate output results.
Description
technical field [0001] The invention relates to a formaldehyde detection method, and the invention also relates to a formaldehyde detection device. Background technique [0002] With the improvement of people's awareness of environmental protection and the emphasis on physical health, there are more and more applications for formaldehyde detection. At present, most formaldehyde sensors used in the market use electrochemical principles for detection. During the detection process, they are easily interfered by other gas components such as toilet water, alcohol, and perfume, which in turn affects the output value of the formaldehyde sensor. [0003] The Chinese invention patent application with the publication number CN109781809A (application number 201910134605.2) "An Artificial Intelligence Calculation Method for Formaldehyde Concentration", in which the disclosed formaldehyde concentration measurement method uses chemical analysis and spectrophotometry to measure multiple se...
